In order to meet ever challenging emission requirements while efficiency of reacting flow devices is increasing, STAR-CCM+ provides advanced reacting flow model capabilities that incorporate finite-rate chemistry and keep the computational time manageable at the same time.

The models work for both, low and high-Mach number applications as well as for multi-phase flows. Examples demonstrating these capabilities will be shown. Validation of soot, NOx and CO against canonical flames using these models will also be presented. Furthermore, flexibility is provided for the users to add source terms as well as material properties and equation of state using field functions to accommodate a wide-range of applications. Moreover, non-transport passive scalars and permeable scalar boundary conditions will be added and discussed.
